Decimal.this

Constructs Decimal from the floating point number using the Ryu algorithm.

The number is the shortest decimal representation that being converted back would result the same floating-point number.

if (
isFloatingPoint!T &&
maxSize64 >= 1 + (T.mant_dig >= 64)
)

maxSize64 <= ushort.max
)

Examples

// float and double can be used to construct Decimal of any length
auto decimal64 = Decimal!1(-1.235e-7);
assert(decimal64.exponent == -10);
assert(decimal64.coefficient == -1235);

// real number may need Decimal at least length of 2
auto decimal128 = Decimal!2(-1.235e-7L);
assert(decimal128.exponent == -10);
assert(decimal128.coefficient == -1235);

decimal128 = Decimal!2(1234e3f);
assert(decimal128.exponent == 3);
assert(decimal128.coefficient == 1234);
